Ubuntu apt-get来的php默认版本现在是php5.3.2
居然对我的代码白屏,

sudo vi /var/log/apache2/error.log

PHP Deprecated: Comments starting with '#' are deprecated in /etc/php5/apache2/conf.d/idn.ini on line 1 in Unknown on line 0
PHP Deprecated: Comments starting with '#' are deprecated in /etc/php5/apache2/conf.d/imagick.ini on line 1 in Unknown on line 0

PHP Deprecated: Comments starting with '#' are deprecated in /etc/php5/apache2/conf.d/ming.ini on line 1 in Unknown on line 0

OK, 错误很明显, 配置文件用错了注释开始符, 把 '#' 改成 ';' 就OK了.
